The only difference between 2.36 and 2.38 is the USB recognition which is exactly what you're after!
I used to run OS9 and Metro 5 using a USB mac connected to a keyspan twin serial port adapter so I didn't need to get a new midi interface. It worked fine.
Moving up to OSX broke the compatibility - the mac could see the interface but couldn't send and receive a signal from it......so I went and got a USB midisport interface.
OS9 and OMS is just such a nasty system.........and you occasionally get crashes / hangs for no reason.
I think most of the time to get mine working right I ran it through the process and if I didn't find what I was after I would run it through the trouble shoot. My synth usually came up as a QS7 or something similar.
This was never an issue as long as you found the program names for your own device.
